Update 2: Multiple early unconfirmed reports from journalists inside Syria have put casualties at 40 killed and 60 wounded, mainly from the Zaynabiyoun Iranian-backed group which was located at the 47th brigade supply base targeted in Hama.

In Aleppo 7 rockets were reported to have exploded in apparently empty areas around Aleppo international airport. There are no reports of injuries or deaths in Aleppo, but images show an area was clearly hit.

As we mentioned previously, the strikes produced a small earthquake as monitors in Lebanon and Turkey recorded seismic activity that registered over 2 on the Richter scale.

Neither Israel nor the United States has yet to formally acknowledge the sizable missile attack, and there’s some speculation in early Western media reporting that it could have been a U.S. coalition action, as it came the same day that pro-Syrian government militias clashed with US-backed Syrian Democratic Forces (SDF) near the eastern city of Deir Ezzor.

Notably, Israeli Prime Minister Benjamin Netanyahu said earlier this month his country will continue “to move against Iran in Syria,” and last Thursday Defense Minister Avigdor Lieberman vowed to strike at any attempt by Iran to establish a “military foothold” in Syria.

Update: Initial reports of mass injuries and perhaps casualties following the Iranian strike appear accurate, and as reporters on the ground located at the Hama National Hospital show, “civilians are donating blood for the Soldiers & Civilians who were wounded by the Israeli Air Strikes tonight.”

Syrian state news reports a possible foreign attack on military bases in Hama and Aleppo provinces, citing multiple reports and videos now circulating which show massive fireballs lighting up the night sky.

Dozens of pro-government social media accounts are claiming an Israeli strike on Brigade 47 weapons depot in Hama Sunday night. Syrian state media says rockets from an “unspecified enemy” hit military locations inside Syria, citing “a new aggression with hostile missiles” but stopped short of identifying the aggressor.

Danny Makki — a well-known journalist reporting from on the ground in Syria — also reports an official military source as saying “A hostile Foreign attack took place at locations in Hama and Aleppo at 10:30 local time tonight.”

Makki further reports“the attacks this evening mainly targeted locations/positions with a strong presence of Iranian backed militias.” This indicates that the likely attacker is Israel, though still not immediately confirmed.

There are also widespread rumors of the recent landing of an Iranian transport plane at Hama Military Airport, possibly targeted in the attack, and reports that explosions were so big due to a direct hit on ammunition warehouses.

Pro-rebel media also appears to be uploading footage of the strike — apparently so big it could be seen for miles — and these sources are also confirming a foreign military attack on government locations. Makki notes the airstrikes “caused an earthquake measuring 2.6 on the Richter scale.”
